摘要：

A novel flame retardant with double functional groups tris(2- (9,10- dihydro- 9- oxa- 10-phosphaphenanthrene-10-sulfide)-ethyl propionate-based) triazine-trione (DOPS-TEAIC) was synthesized from 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-sulfide(DOPS) with tris(2-acryloxyethyl) isocyanurate(TEAIC). Its structure was determined by Fourier transform infrared spectroscopy, nuclear magnetic resonance and mass spectrometry, and it was applied in epoxy resin (EP) to prepare EP/DOPS-TEAIC. The effects of DOPS-TEAIC on the thermal stability, flame retardancy and thermal degradation behavior of EP were studied by thermogravimetric analysis, vertical combustion, limiting oxygen index, cone calorimeter, thermogravimetric- infrared spectroscopy and pyrolysis gas chromatography- mass spectrometry, and the flame retarding mechanism was deeply analyzed. The results show that flame retardant DOPS- TEAIC can improve the thermal stability, char residue content and flame retardancy of EP, and reduce its peak heat release rate (PHRR) and average heat release rate (av- HRR). When the mass fraction of DOPS- TEAIC is 10.0%, the LOI value of EP/DOPS- TEAIC increases to 33.4%, reaching UL- 94 V- 0 level, and its PHRR and av- HRR values are decreased by 34.2% and 22.8% respectively, compared to pure EP. The flame retardant DOPS-TEAIC plays a flame retardant role in gas phase mainly through dilution and free radical quenching. © 2024 Sichuan University. All rights reserved.
